CHARGING-HOPPER FOR GAS-PRODUCERS.

SPECIFICATION forming part of Letters Patent No. 655,931, dated August 14;, 1900. Application filed December 20, 1897. Serial No. 662,518- (No model.)

To aZZ whom it may concern:

Be it known that I, GEORGE ROBERTSON HIsLoP, engineer and gas-Works manager, of the Gas Works, Paisley, in the county of Renfrew, Scotland, have invented certain new and useful improvements in apparatus for charging gas-producers and gas or shale-oil retort-furnaces with hot residual coke, (which has been patented in GreatBritain by Letters Patent dated February 26, 1889, No. 3,391,) of which the following is a specification.

The object of my invention is to provide simple and efficient means for directly charging gas or shale-oil retort furnaces or ovens with hot residual coke from the retorts heated by such furnaces or ovens in lieu of, as is usual, transferring the hot coke into bogies and charging the furnaces therefrom, the means consisting of a hopper pivoted upon a mouthpiece in the crown-plate of the oven or furnace and adapted upon, the opening of a door or disk normally covering said mouthpiece to tilt into position to receive the hot residual coke from the retorts above. To that end I cast or otherwise form a mouthpiece upon a crown-plate which is placed and bolted on top of the projecting breastwork of the retort-oven and over the ordinary cleaning and charging doors and form therefrom a chute extending downward and rearward through the upper front wall of the furnace at such an inclination as to discharge the fuel at or near the middle of the oven or furnace. This mouthpiece is furnished with a self-sealing door operated by levers and has hinged or jointed to it a hopper which may be raised and held by a catch close up against the front wall of the retorts in an approximately-vertical position or lowered and retained by the same or a separate catch in a position in which it forms an inclined plane with the re tort-wall, and through the mouthpiece when in its inclined position the hot residual coke drawn from one or more of the retorts is discharged directly into the oven or furnace.

The charging arrangement is placed in front of and attached to any oven of gas or shaleoil retorts, but more particularly to retorts heated by means of an oven placed immediately under the retorts, and in order to its more convenient application the front portion of the oven is preferably built in projec tion beyond the front line of the retort.

The invention is illustrated by the accompanying drawings, in which- I Figure 1 is a front elevation, and Fig 2 a side elevation, showing the hopper and part of the front of the retort-oven, Fig. 3 being a detailed view of the door covering the chute leading from the hopper.. Fig. at is an enlarged plan of the jamming or lockin g device. Fig. 5 is a central section of the cover-plate, and Fig. 6 is an enlarged view of the adjusting means for axle Z.

The crown of the oven is terminated, preferably, in an arch of brickwork A,and through the top a suitable port or chute B is formed for the passage of the coke from the retorts into the oven. The upper or arched portion of the retort-oven is bound together by metal jacket-plates G, securely bolted to front plate D of retort and front of oven E, respectively, the said front plate being furnished with an upper door F to facilitate cleaning and a lower one (not shown) for withdrawing the ashes from the oven. On the top of said jacketplates and over the opening B for the passage of the coke into the oven a cast-iron crown-plate G, with doorway H, preferably oval in form, is fixed on and at a suitable angle or inclination from the face of the oven. The doorway H is furnished with lugs h and is planed on its face and fitted with a corresponding door or disk I, whose thickness is increased from the back toward the front, said door being hinged on a pin t, passing through one of the lugs hand being held by a jam-' min g-lever J, central on another pin 1" on the other lug, one end of said lever J entering a recess 1 in the door I and bearing against said door to retain it in its closed position. The door or disk I is provided with a handle I, by means of which it is turned upon its pivot 71 when the jamming-lever J is released, The disk I at the back passes under plates j, bolted upon and slightly overlapping the inner faces of stop-pieces h, secured to rearward extensions of the lugs h, these together forming pockets which define the travel and fix the position of the disk I. On the top of the pins it, hinging' the disk I and jamming-lever J,

adjustable journal-bearingsare provided to receive and carry pins Z of the charginghopper L. These adjustable bearings may be constructed in any-manner, provided they admit of raising or lowering the pivot-eyes for the axis-pins l to suit hoppers having a greater or'less distance from the center line of the axis-pins to thelower edge of the hopper. For example, they may consist of eyepieces K, having holes for pins 1 near the upper ends and also elongated slots K, Fig. 6, below said holes. The bearing or eye pieces K are placed beside the standards 1', rigidly supported by the pins 0; t" of the door I and jamming-lever J, respectively, the pieces K being secured at the desired height by bolts K with suitable nuts thereon, Figs. 1 and 6. In Fig. 1 pieces K are in their lowermost position. The charging-hopper L'is preferably ovular in form and expanded at the mouth to the width of the retort or retorts above, from whence the fuel is discharged into the oven or ovens. The hopper is placed, preferably, immediately under the central retorts of the oven.

When the furnace or oven is who charged with the hot residual coke from the retorts, the jamming-lever J is actuated so as to allow the disk or door I to turn upon its pivot 1' until the mouthpiece Bis uncovered. Simultaneously with the uncovering of the mouthpiece B the hopper L, which previously rested upon the disk or door I, tilts upon its axispin Zinto the position'shown by dotted lines to receive the fuel from the retorts. By turning the disk or door I back to its original position under the hopper B the latter is raised by the door or disk, acting as awedge, until the outer edge of said hopper is up to or within the line of the retort-mouthpieces.

The invention has been described only in its application to retort-ovens; but it is obvious that it may be used in connection with anyform of gas-producer into the oven or ovens of which fuel is discharged from above.

Having now described the invention, what I claim, and desire to secure by Letters Patent, is

1. The improved apparatus for charging gas-producers or heating-furnaces of gas and other retorts with hot residual coke consisting of a crown-plate having in it a mouthpiece opening to an inclined charging-chute a doorway thereon furnished with a self-sealin g Wedge-like door ordisk hinged or pivoted thereto, and a charging-hopper jointed to the mouthpiece or doorway, and adapted to tilt into position to receive the fuel from said retorts or producers, by the movement under it of the disk or door substantially as described.

2. The combination with an oven, of a crownplate G, a suitable mouthpiece B, a doorway H fixed at an angle above the crown-plate, a pivoted wedge-like door-plate I, said plate having a handle I, a locking device, adjustable journals K, and hopper L pivoted on said axis.

Signed at Glasgow, in the county of Lanark, Scotland, this 6th day of December, 1897.
